same line so that the power is transmitted from the driving wheel to thedriven pinion in a direct 01 straight line7 whereby cramping and hardrunning of said wheels is avoided 5-and an easy working machineisproduced.

By depressing the treadles alternately the spindle D and thepartsconnected therewith may' be rotated continuously and; at a uniformspeed. If desired this rotatioh ma be .to produced by oscillating thetreadles in u ison orby oscillating but one of the treadles.

Means for supporting the tool or other article to be ground are providedand preferably constructed as follows: l represents a supl5 porting rodor stem projecting horizontally forward from the left 4hand part of thehead stock.' i is an arm or rest having a sleeve il Aat its inner endwhich is mounted on the rod l. This arm may be moved lengthwise of therodl and swung into a horizontal osition across the front of thegrinding w eel,

as shown by 'dotted lines in Fig. 2, for` supporting the article to beground. The armi is held in position on the rod l by a set screw i2. Forholding tools or articles tangentially to the .periphery 'of thegrinding wheel to lbevel the same, a supplementary support or rest. isprovided consistingof a horizontal, shelf J and an attaching shank jdepending l 3i) from the inner end of the shelf. wWhen it is desired touse this supplementary rest the arm l 'i swung downwardly into a'pendent position and .the shank; of the supplementai secin'ed l"r cretob'v a bolt j1 passing throng a longitudinal/ slot said shank and asimilar slet y in said infn, ZJhewn in i and. l By raising or loweringthe supi' Y men or tilting the saine on the arm t the be adjusts vtdiffer- 40 ent an s tn the grr d. ne a'neel as 'A D by le article to beurs-und. li rej tall spindle or dean. center which enga with the re: endof the live spindle when the same is long and carries the saw, shown inFigs. and 201' the same ,e wth4 short live center for d Z y ve spinaleann is adjusted 'hcreon by screw lc and held in place after adjustmentby se'tscrew 7c.

'l5/hen the machine is used for turning, an ordinary tool rest lf2,shown by dotted lines in yFig.. 2, is moimted on a horizontal bar l1wliich is arraizgnad lenigtlnvise in front of spindle center Ltze-.djwcvided at one end a sie ze Zwhicli is ly mounted red l; projecting rfrom .and side of the place thereon by a sot screw Z2. When l; held inthefront har L is not in se the same can be swung dowi'iwardly on therodZ1` out of the way.

For 'the purpose of `adapting the machine ythe live spindle, a rear barconnectin for turning articles which vary considerably in length eitherthe head or the tail stock'or both may be shifted on the table orsupport carrying the same to suit the work.

' In order to enable the two stocks to be seciirely connected forstiilening the machine and still permit of adjusting the same toward andfrom each other, a bar M is provided which is -arran ed horizontally andlengthwise in rear of t e spindle center and rigidly secured at one endto one of said stocks while its opposite end is adjustably connectedwith the other stock by a bolt or screw m passing through ,alongitudinal slot fm1 in said bar and into the last mentioned 30 stock.4Y N re resents a table for sup )orting articles while fieing sawed. Thistable is arranged horizontally and extends transversely across thespindle centers, a slot n being formed in g5 the table through which theupper part of lthe saw projects, as shown in Figs. 1 and 3.

The article to be cut is placed on this table and guided reliablythereon while being cut by the saw. Means are provided for enabling thetable to be adjusted both vertically and .longitudinally and adapt thesame to the position of the saw on the live spindle and also to saws ofdifferent diameters and to permit of 'using spindles of dilferent 95lengths. The preferred means for this purpose comprise two dependinglugs o, o arranged at the front and rear ends of the table, and twocoupling pieces. Each of the latter is of angular' form and providedwith a vertical web or flange p and a horizontal flange p1. Thehorizontal flange of each coupling piece is adjustably connected withthe adjacent horizontal supporting bar by a-bolt gf passingthrough saidflange and the slot of said bar and the vertical llange cf the couplingpiece is adjustably connected with the adjacent ilange o of the tablebya'bolt r passing through slots r1, r2 in said flanges. By looseningthcbolts r and g of both coupling )ieces the table may beadjusted bothaxially and radially relatively to 'the saw to suit t dze and posi vonof the latter.

l l .en as iny invention:

machine of the character described com- 120 i a head stocl a tail stock,a live lcd in said head stock, a dead ted on the tail stock and'engaglive spindle, a saw mouritpd on U said stoclrs and having alongitudinal slot, alfront bar connected with the head stock andl havinga longitudinal slot, a table having a slot which receives-said saw andprovided at its ends with depending [langes 'each of whichv 130 has avertical slot, and means lor adjustably connecting each end of the tableWith the adjacent bar consisting of an angular coupling piece having aVertical flange Which is slotted lengthwiseand a horizontal flange, abolt connecting the Vertical flan e of each coupling piece and 'one ofthe f epending flanges of the table and passing through the slotsthereof, and a bolt connecting the horizontal flange of the couplingpiece and the 1o adjacent bar and passing through the slot of thelatter, substantially as set forth.
